This concerns keyboard navigation into the rows of a list-view (such as the details view in Nautilus, or the library in Rhythmbox).

You can tab-into it and tab-out, but you can't shift-tab back into it.


Reproduction:

1.  [example] Open Rhythmbox.
2.  Press tab to cycle through UI elements, until you reach the list view with columns.
3.  Tab once into the list columns.
4.  Tab once into the list view rows.
5.  Press tab again to move focus to the next UI element (away from the list view).
6.  Try to shift-tab back to the list view.


Observation:
Shift-tab does not return focus to the list view.  It instead jumps all the way back to the list columns.


Expectation:
Since tabbing forward goes in the order:

List Columns -> List Rows -> Other UI

then tabbing backwards should go Other UI -> List Rows -> List Columns.


The list view is included in the forward tabbing order.
It should be included in the backward tabbing order.

Currently you can never enter the rows of a list view using shift-tab, though it works fine with tab.  This is inconsistent.
